3. PRECAUTIONS FOR DATA PROTECTION
3.1 Battery-backed up Data
The SCNT board is provided with a function for backing up data in control
processing memory (SRAM) and image storage memory (DRAM) by lithium
battery, and rechargeable battery, even if a power interruption occurs, or the power
cord is disconnected by accident.
The back up time for image data with the secondary vanadium-lithium
battery is approximately 12 hours. When the back up time is exceeded,
the image data is deleted. Please print out the data before shutting off
the power. If the reception image data cannot be printed out due to
printer engine trouble, transfer the stored reception image data to
another fax. For details, see this Chapter, 3.2.2 Reception image data
